Because of its fantastic headline read/write speeds, there is often a lot of interest in this drive. It's not available in 16GB so I couldn't include it in the standardized tests. Quickly looking at the 64GB Kingston HyperX 3.0 (manuf.) claimed seq r/w speeds 225/135 @ £78 or $100. Compared to the November leader - Sandisk Extreme 64GB version (manuf.) claimed r/w 190/170 @ £45 or $79. The extreme is significantly better value, and has much much faster 4K write speeds. [Nov '12 USBFlashPro]
